Dabrafenib and Trametinib in Treating Patients With BRAF Mutated Ameloblastoma

This pilot clinical trial studies dabrafenib and trametinib in treating patients with ameloblastoma and a specific mutation (change) in the BRAF gene. Dabrafenib and trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Stanford is currently accepting patients for this trial.

   least 6 months after treatment with dabrafenib

   - Able to swallow and retain oral medication and must not have any clinically
   significant gastrointestinal abnormalities that may alter absorption such as
   malabsorption syndrome or major resection of the stomach or bowels

   - Left ventricular ejection fraction equal to or greater than normal

Exclusion Criteria:

   - No prior treatment with agents targeting BRAF mutant tyrosine kinases or radiation of
   target lesions

   - Invasive malignancy other than ameloblastoma within 3 years, excluding curatively
   treated basal cell carcinoma, and other highly curable cancers such as early stage
   cutaneous squamous cell carcinoma (T1 NO) cervical carcinoma in situ (CIS), early
   stage prostate cancer, thyroid cancer or breast cancer

   composition to dabrafenib

   - Concomitant use of strong inhibitors (e.g., ketoconazole, nefazodone, clarithromycin,
   gemfibrozil) or strong inducers (e.g., rifampin, phenytoin, carbamazepine,
   phenobarbital, St John's wort) of cytochrome P450, family 3, subfamily A, polypeptide

   - A history of retinal vein occlusion (RVO)

   - Congestive heart failure NYHA class III or worse (Marked limitation of physical
   activity. Comfortable at rest. Less than ordinary activity causes fatigue,
   palpitation, or dyspnea.)

   - A history of acute coronary syndromes (including myocardial infarction or unstable
   angina), coronary angioplasty, or stenting within 6 months
